the organic process of growing older and showing the effects of increasing age
According to the United Nations (UN) Population Division report for the 2002 World Assembly on Ageing, "population ageing is unprecedented, without parallel in human history and the twenty-first century will witness even more rapid ageing than did the century just past."
the United Nations agency concerned with the international organization of food and agriculture
UN Food and Agriculture Organization (FAO) officials warn that 370 million people could face chronic famine by 2050 and that an estimated population increase to more than 9 billion people by 2050 suggests that the world will need to produce 70 percent more food than is currently produced to avoid widespread hunger.
increase in the number of people who inhabit a territory or state
Population growth continued to accelerate, taking only thirty years to grow from two to three billion and then just another fifteen years to grow to four billion.
a contraceptive in the form of a pill containing estrogen and progestin to inhibit ovulation and so prevent conception
Such effective contraception measures as the birth control pill, used by an estimated one hundred million women worldwide, are available for those who want to restrict the size of their families.
an expected time to live as calculated on the basis of statistical probabilities
Over the last century, such advances in medicine as the discovery of antibiotics and improved health care and sanitation have led to dramatic increases in life expectancy.
Along with a potential infectious disease pandemic from a highly lethal virus related to H5N1 avian flu, AIDS is perhaps the biggest public health threat to the global population, particularly in Africa, where gains in life expectancy have been wiped out owing to the numbers succumbing to the disease.
Not only do people consume resources for food and energy, their activities tend to damage and degrade the environment through atmospheric pollution and soil erosion.

a person who is a chief administrator (as of the United Nations)
At a November 2009 conference in Rome, United Nations Secretary General Ban Ki-moon called for a "single global vision" to tackle population, climate, and food issues.
The most significant environmental problem that has been linked to population growth and increased consumption is global warming, which threatens widespread climate change.
birth control by the use of devices (diaphragm or intrauterine device or condom) or drugs or surgery
Such effective contraception measures as the birth control pill, used by an estimated one hundred million women worldwide, are available for those who want to restrict the size of their families.
the preservation of mental and physical health by preventing or treating illness through services offered by the health profession
Over the last century, such advances in medicine as the discovery of antibiotics and improved health care and sanitation have led to dramatic increases in life expectancy.
an organization of independent states formed in 1945 to promote international peace and security
According to the United Nations (UN) Population Division report for the 2002 World Assembly on Ageing, "population ageing is unprecedented, without parallel in human history and the twenty-first century will witness even more rapid ageing than did the century just past."
a disease transmitted only by a specific kind of contact
Along with a potential infectious disease pandemic from a highly lethal virus related to H5N1 avian flu, AIDS is perhaps the biggest public health threat to the global population, particularly in Africa, where gains in life expectancy have been wiped out owing to the numbers succumbing to the disease.

the diversity of plant and animal life in a particular habitat (or in the world as a whole)
In addition to the negative consequences of unchecked human growth upon the quality of human life, some population control advocates argue that increased human population threatens biodiversity.
move from one country or region to another and settle there
Many people migrate to the city in search of opportunities to earn money, but insufficient employment may merely shift poverty and its accompanying problems from rural to urban areas.
a statistic characterizing human populations (or segments of human populations broken down by age or sex or income etc.)
The UN Population Division report for the 2007 World Assembly on Ageing states that the world's aging population will produce an unprecedented demographic shift as "the number of older persons is expected to exceed the number of children for the first time in 2047."
an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes)
The most significant environmental problem that has been linked to population growth and increased consumption is global warming, which threatens widespread climate change.
the ratio of live births in an area to the population of that area; expressed per 1000 population per year
The aging of the population, along with decreasing birth rates in many countries, means that there may not be enough younger people working to support their elders financially through pensions and social support.
(geology) the mechanical process of wearing or grinding something down (as by particles washing over it)
Not only do people consume resources for food and energy, their activities tend to damage and degrade the environment through atmospheric pollution and soil erosion.

a severe shortage of food (as through crop failure) resulting in violent hunger and starvation and death
UN Food and Agriculture Organization (FAO) officials warn that 370 million people could face chronic famine by 2050 and that an estimated population increase to more than 9 billion people by 2050 suggests that the world will need to produce 70 percent more food than is currently produced to avoid widespread hunger.
